MC74VHC1G32DFT2G-Q

Inverter Gates Overview

The MC74VHC1G32DFT2G-Q is a single 2-input OR gate from the onsemi VHC series, designed for operation between 2.0 V and 5.5 V supply voltages. It features CMOS-level input thresholds and provides over-voltage tolerant inputs and outputs up to 5.5 V, enabling safe interfacing between 5 V and 3 V circuits. The device supports partial power-down protection via IOFF functionality and delivers source/sink currents of 8 mA at 3.0 V. It is qualified under AEC-Q100 standards and is PPAP capable, making it suitable for automotive applications requiring unique site and control change requirements.

Inverter Gates Feature Summary

• AEC-Q100 qualified with PPAP capability for automotive and high-reliability applications
• CMOS-level input thresholds with over-voltage tolerance up to 5.5 V for mixed-voltage interfacing
• Supports partial power-down mode through IOFF protection against current leakage
• Available in compact SC-88A surface-mount packages

Inverter Gates Applications

• Automotive electronic systems requiring AEC-Q100 qualification
• Interfacing 5 V logic circuits with 3 V logic circuits
• Battery backup systems where voltage mismatch protection is required
• Hot insertion scenarios involving supply voltage mismatches

Inverter Gates Procurement Notes

Verify that the suffix -Q indicates compliance with AEC-Q100 qualification and PPAP capability, which are specific to automotive and controlled manufacturing environments. Confirm the SC-88A package type matches the design footprint. Ensure the ordering code includes the correct date code and Pb-free indicator as specified in the manufacturer's documentation to guarantee component authenticity and traceability.

Inverter Gates Selection Notes

Select this component when an OR gate function is needed within the 2.0 V to 5.5 V operating range. It is appropriate for designs requiring robust over-voltage tolerance on both inputs and outputs. Consider this part if automotive reliability standards such as AEC-Q100 are mandatory. The SC-88A package offers a small footprint suitable for space-constrained PCB layouts.

Inverter Gates Part Context

This device belongs to the MC74VHC1G32 family of single 2-input OR gates. It shares functional characteristics with the MC74VHC1GT32, though the latter utilizes TTL-level input thresholds instead of CMOS levels. Both variants offer similar electrical performance and packaging options, allowing designers to choose based on specific input logic level requirements while maintaining compatibility with standard VHC series interfaces.
